They were transported to the laboratory in a selective mycoplasma transport medium and in phosphate buffer solution. The specimens were inoculated into specific broth and solid medium for culture. Characteristic mycoplasma colonies were determined with Diennes{\textquoteright} stain and examined microscopically. For PCR, samples were analyzed with genus specific primers. The primer sets, which were originally designed in our laboratory, amplified a 465~bp fragment (Mycoplasma genitalium), 559~bp fragment (Ureaplasma urealyticum), and 630bp fragment (Mycoplasma hominis). Samples containing a band of the expected sizes for mycoplasma strains were subjected to digestion with a restriction endonuclease enzyme.RESULTS: Of the 210 samples, mycoplasma strains were isolated from 83 patients (39.5\%), (23 mycoplasma isolates, 11\%; and 69 ureaplasma isolates, 32.9\%) by using a selective mycoplasma isolation media. Using PCR, a total of 120 (57.1\%) samples were found to be positive for mycoplasmas (28 mycoplasma spp., 13.3\%; and 67 ureaplasma spp., 31.9\%) and co-infections with both species were detected in 25 samples (11.9\%).CONCLUSION: The PCR was found to be highly sensitive when genus specific primers were used for diagnosis of genital mycoplasmas in comparison with culture.}, issn = {0379-5284}, URL = {https://smj.org.sa/content/30/11/1401}, eprint = {https://smj.org.sa/content/30/11/1401.full.pdf}, journal = {Saudi Medical Journal} }
